alright so pretty much i was at the local toyota dealer and i got to see a supra with compound turbo setup
pretty much it was like a twin turbo kit but it works like a single turbo but it offers 0 lag because you have one super small turbo that spools up for great low end but when it reaches a certain boost level, a wastegate will divert as much exhaust gases to the bigger turbo which would have spooled up by then
this video explains it better then i can but i was wondering how possible would it be to do something like that on the 370z?
